Vicente Fox visits Stanford University

A pair of presidents drew hundreds to Stanford's Business School. Former Peruvian President Alejandro Toledo introduced Mexico's former President Vicente Fox.

Fox's focus was supposed to be on economic growth and poverty in Latin America, but given Colombia's recent attack on rebels in Ecuador and Venezuela's decision to arm its border -- conversation shifted.

"With today's crisis that is facing Venezuela and President Chavez meddling with the affairs between Colombia and Ecuador, we feel American states should act more for democracy," said an audience member.

Toledo and Fox admit, as former presidents, some Latin nations have asked they help mediate the situation.

They're hoping the Organization of American States will intervene first.

"I don't foresee an escalation of greater conflict than this. I hope the OAS will act as soon as it can," said Former Peruvian president Alejandro Toledo.

Venezuelan president, Hugo Chavez is at the center of the Colombian controversy -- as far as these presidents are concerned.

"What will happen to Bill Gates, Microsoft, if we don't accept them in the rest of the world? We say, no we don't want that because we'll lose our jobs'. I mean, it's, they're only showing their lack of capacity to understand how the economy runs," said Fox.

Fox agrees NAFTA does need to change. He wants it to expand, to include even more countries.
